2AGP4K2 FBI Laboratory analysis of Castor Beans used to manufacture the highly poisonous agent Ricin. Ricin (/'ra?s?n/ RY-sin), a lectin (a carbohydrate-binding protein) produced in the seeds of the castor oil plant, Ricinus communis, is a highly potent toxin. A dose of purified ricin powder the size of a few grains of table salt can kill an adult human. The median lethal dose (LD50) of ricin is around 22 micrograms per kilogram of body weight if the exposure is from injection or inhalation (2 milligrams for an average adult).

Illustration of a teenage girl who is the offspring of a Neanderthal (Homo neanderthalensis) mother and Denisovan (Homo sapiens denisova) father. A bone fragment with this hybrid ancestry was found in the Denisova Cave in Russia. The bone belonged to a female who was at least 13 years old and died around 90,000 years ago. It was known from genetic analysis of other fossils that the two species had interbred, but this is the first first-generation offspring of such a pairing to be found.
